How to Draught Proof Doors

There are several ways of draught-proofing doors. Most of them consist of fitting strips of proofing material to the edge of the door or to the frame. The material may be extruded rubber strips of the type shown in and this type of strip may be nailed to the edge of the door if space permits, or to the door-stop. Proofing strips are effective, but they are rather unsightly and another method of draught-proofing is recommended.

This consists of affixing thin strips of phosphor-bronze to the doorframe. The method of fixing is shown in the video below and the image also, which shows how the thin strips are nailed in position inside the framework against the door-stop. The strip bronze is supplied in cartons and there are several different branded types, each with its own container instructions. Most of these strips may be ‘sprung’ and this is easily done with a special tool supplied with the draught-proofing outfit. The tool impresses a line along the length of the strip which causes the inside edge to be raised slightly from the frame, so that when the door is closed the sprung edge is seated firmly all round against the edge of the door.

This method of draught-proofing is quite easy to carry out, but care should be taken not to buckle the thin metal strips when attaching them to the door-frame.

 

Most of the draught from a door enters through the space under the door and above the floor, and obviously this cannot always be filled in if there is a carpet laid in the room. This difficulty may be overcome by fitting rising-butt hinges. The effect of rising butts is to raise the door as it opens, thus lifting it over edges of rugs or carpets.

This consists of a strip of 2-in. by 1-in by softwood, the top forward edge of which is rounded off with a small plane. A groove is cut in the bottom edge to take the flange of a strip of draught-proofing rubber of the type previously mentioned. The stop is secured to the outside of the door by means of hinges as shown.

Before affixing the draught-stop to the door it should be placed in position against the bottom of the door-stop, a shaped portion of which should be cut away with a chisel to accommodate the ends of the stop. The action of the stop when the door is opened is such that it rides easily over the edges of rugs and carpets. When the door is closed the notches in the stop seat firmly against the ends of the draught-stop, forcing the rubber tube against the floor to effect a perfect seal.

If it is found that the action of the stop is sluggish when the door is opened, this may be overcome by fitting a mousetrap spring under the centre of the stop.
